Product Overview
The F-122CU series represents a premium line of 5-inch full-range, acoustically processed ceiling loudspeakers engineered to deliver superior sonic fidelity, ultra-wide uniform sound dispersion, and reliable emergency paging performance. Built around a specialized bass-reflex enclosure, these units employ an acoustic diffuser to maximize off-axis high-frequency distribution, providing a smooth conical coverage zone up to 180 degrees.
Within Pakistan, SKYRS stands as the exclusive distributor, integration authority, and technical partner for the entire F-122CU commercial loudspeaker range.

Deployment and Installation
Acoustic placement, structural ceiling mounting, and safety anchoring are handled completely by certified on-site technicians from SKYRS across Pakistan.
Ceiling Cutout and Tile Bridge Loading
The installation of all F-122CU variations requires a precision circular ceiling cutout hole measuring exactly 200 mm in diameter. To avoid ceiling panel sagging or fracturing inside standard acoustic drop-ceilings, use the structural tile bar bridge and reinforcement rings included in the installation package. Position the support rails across the ceiling grid structure to transfer the 4.4 kg speaker weight away from the ceiling panel material.
Plenum Environment and Safety Tethers
For air-handling plenum networks, secure the integrated metal back-can assembly utilizing the heavy-duty quick-mount rotating toggle clamps. Connect an independent structural steel safety cable from the primary M6 safety anchor point on the rear plate of the loudspeaker enclosure directly to a load-bearing building support wire or concrete beam above the false ceiling plane.
System Configuration
Transformer tap matching, balancing matrix configuration, and specialized active equalization must be managed by certified technicians to keep your product warranty active.
Step 1: Front Baffle Power Tap Selection
Before snapping on the low-profile paintable steel mesh grille, adjust the input power matching tap. Use a flathead tool to rotate the selector switch located on the front baffle. Select between 30W, 15W, 5W, 1.5W, or 0.5W when operating over 70V commercial background music distributed loops, or set to 8/16-Ohm mode for direct low-impedance configurations.
Step 2: Terminal Block and Loop-Through Termination
Strip system cable wires down to bare copper (matching AWG No. 14 to 18 specifications). Insert the lines into the removable four-pole locking input connector. Connect incoming amplifier feeds to Terminals 1 and 2, then use Terminals 3 and 4 as an internal loop-through bridge to daisy-chain the continuous speaker line to neighboring F-122CU nodes.
Step 3: Processor Equalization and Level Balancing
The F-122CU architecture relies on active digital processing to deliver flat frequency optimization. Apply the factory-specified acoustic correction filters via a dedicated digital speaker processor or the specialized controller module within your central amplifier system. Run uniform pink noise profiling across the environment to adjust overall system gains and confirm proper acoustic phasing.
Service and Configuration Availability
The supply of all genuine F-122CU Wide-Dispersion Ceiling Speaker variants, mounting bridge hardware, on-site ceiling deployment, physical installation, and precise processing network configuration are available exclusively through SKYRS in Pakistan. Third-party system installations, improper transformer line loading, or unverified modifications will void the local five-year commercial replacement warranty. To schedule sound pressure mapping surveys, evaluate corporate spatial audio plans, or schedule commissioning engineering staff, contact the SKYRS Pakistan project implementation desk.
